Abstract
An ultra light weight poppet valve which includes elements for controlling the temperature of the valve during operation. The valve is of the type which is formed as an elongated cup having a flared open end to which a cap is fixed and in which an extremely thin-wall section is maintained all the way to a closed tip end. Temperature control elements include multiple thin-walled elements in nesting relationship to define multiple interior chambers, and a plug member received within the stem portion of the valve and maintained in place by inwardly deflecting the stem portion.
